Re: Alt Text vs AD

They are the same from the viewpoint that the purpose of alt text and audio description is to convey visual information in a way that makes it possible for someone who cannot perceive that information visually.

However, they are very different when it comes to implementation. Alt text is just text--typically used to describe the important information provided by a static image. Audio description is a spoken audio track where someone describes the important visuals of a video.

Subject: [WebAIM] Alt Text vs AD

Hello everyone, some of us are discussing the differences (if any) between alternative text vs audio description. Does anyone see them as the same? If different, how so? Thanks for any input to diffuse the difference of opinion. Thanks.
